Reset the filter indicator light after you install a new filter
After you put a new water filter into your Samsung fridge, the filter indicator light stays on until you tell the fridge the filter is fresh. The reset process takes about 10 seconds and works the same way on most Samsung models—you hold a button until the light changes color or turns off. The exact button and the exact light behavior depend on your model, so check your manual first, but the general steps are the same across the brand.
The reason you need to reset it: Samsung fridges track how long a filter has been in use. The light reminds you when the filter is old and needs replacing. Once you swap in a new filter, the fridge's counter needs to restart from zero, and that reset button does that job. If you skip this step, the light will keep warning you even though your filter is brand new.
Key Takeaways
- Most Samsung fridges reset the filter light by holding a dedicated button on the control panel or inside the fridge for 3 to 10 seconds until the light changes color or blinks.
- The reset button location varies by model—check your manual or the filter housing itself, where Samsung often prints instructions.
- You must reset the filter light after installing a new filter, not before, or the fridge will not track the new filter's age correctly.
- If the light does not respond to the reset button, the filter may not be seated properly, or the button itself may need a firmer press.
Locate the reset button on your specific model
Samsung puts the reset button in different places depending on the fridge model. On many French-door and side-by-side models, the button is on the control panel on the front of the fridge, usually labeled "Filter Reset" or "Ice/Water Reset." On some models, especially older ones, the button is inside the fridge near the water filter housing itself—often on the back wall or on the side wall where the filter cartridge sits.
The fastest way to find it: open your fridge and look at the water filter housing. If you see a small button or a label with reset instructions printed directly on the plastic, that is your answer. If not, check the front control panel. Your owner's manual will have a diagram showing the exact location for your model number. You can find the manual by searching "Samsung [your model number] manual" online, or by calling Samsung customer service at 1-800-726-7864.
Some newer Samsung models with a digital display on the fridge door use a touchscreen menu instead of a physical button. In those cases, you navigate to Settings or Filter Status on the display and select Reset Filter. The manual will walk you through the menu path.
Press and hold the button until the light resets
Once you have located the button, press and hold it. Most Samsung fridges require you to hold the button for 3 to 10 seconds. You will see the filter light change—it may turn green, turn off completely, or blink once and then go dark. That color change or blink is your signal that the reset worked.
If nothing happens after 10 seconds, release the button and try again. Sometimes the button needs a firmer press than you might expect. If the light still does not change after two or three attempts, the filter cartridge may not be installed all the way. Remove the filter, push it back in until you hear or feel a click, and try the reset button again.
Make sure the filter is seated correctly before resetting
A filter that is not fully inserted will not trigger the reset properly, and the fridge may not dispense water at all. Before you press the reset button, confirm that the new filter is pushed all the way into its housing. Most Samsung filters slide in horizontally or twist in like a light bulb, depending on the model. You should feel resistance and then a solid click when it is seated.
If the filter is loose, water may leak from the connection point, or the fridge may show an error code instead of letting you reset the light. Tighten or reseat the filter, wipe away any water around the housing, and then try the reset button. If water is still leaking after you have pushed the filter in firmly, the filter cartridge itself may be defective, and you should replace it with a new one.
What to do if the reset button does not work
If you have held the button for 10 seconds and the light has not changed, try these steps in order. First, unplug the fridge from the wall outlet for 30 seconds, then plug it back in. This resets the fridge's control board and sometimes clears a stuck filter light. Wait a minute for the fridge to power back up, then try the reset button again.
Second, check that you are pressing the correct button. Some Samsung models have multiple buttons on the control panel, and pressing the wrong one will not work. Look at the label above or next to each button to confirm you have the right one. If your manual shows a diagram, match the button location in the diagram to the buttons you see on your fridge.
Third, if the button feels stuck or does not click when you press it, the button itself may be broken. In that case, you will need to contact Samsung service or a repair technician. A broken reset button is not something you can fix yourself, and the fridge will continue to show the filter warning even though the filter is new.
Reset the filter light on ice-maker-only models
Some Samsung fridges have an ice maker but no water dispenser on the door. These models still have a water filter inside, and the reset process is the same—find the button, hold it for a few seconds, and wait for the light to change. The button is usually inside the fridge near the ice maker or on the back wall where the filter housing is located.
Check your manual for the exact location, because these models vary more than the standard side-by-side or French-door designs. If you cannot find a reset button and your manual does not show one, your model may use a touchscreen menu reset instead. In that case, look for a Settings or Filter option on any digital display your fridge has.
Frequently Asked Questions
Do I reset the filter before or after I install the new filter?
Always reset after you install the new filter. The reset tells the fridge to start counting the age of the filter from zero. If you reset before installing, the fridge will not track the new filter correctly, and the light may come back on too soon or not at all.
What if the filter light is still on after I reset it?
The light should turn off or change color when ready after a successful reset. If it stays on, the filter may not be fully seated, the reset button may not have worked, or the filter itself may be defective. Try reseating the filter, then reset again. If the light still does not change, unplug the fridge for 30 seconds and try once more.
Can I reset the filter light without replacing the filter?
Technically yes, but you should not. Resetting the light tells the fridge the filter is new, which is only true if you actually installed a new filter. If you reset without replacing, the fridge will not warn you when the old filter gets dirty, and your water quality will suffer.
How often do I need to reset the filter?
You reset the filter light once every time you install a new filter cartridge. Samsung recommends replacing the filter every six months, depending on your water quality and how much water you use. Each time you put in a new filter, you reset the light.
Where do I buy a replacement Samsung water filter?
Samsung filters are sold at appliance stores, big-box retailers like Home Depot and Lowe's, online at Amazon, and directly from Samsung's website. Make sure you buy the correct model number for your fridge—the model number is printed on the filter housing or in your manual.
